Anywho, just more data, FYI.
Interesting that you got a dyno proven 46 ft/lb increase in torque. That is substantially more than the 30. That type of to the wheels gain certainly does not hurt the cost/benefit ratio. Wonder if the N55 would see the same gains? Probably not since the consensus appears to be that the N54 responds to tuning better.

Anyway, thanks.
